The Cat In the Hat (Seussical) would def. be one of my favorites. The role was so much fun to play because I got to switch personalities (and accents) all through the show. Plus, we had an awesome cast that really fit their parts. It was also the first time we had sold out a musical, so that was insanely exciting.
My other favorite role was Katisha in "The Mikado". My character was larger-than-life acting and I had a blast with the delivery of some of my lines and actions. It was a really fun show to do and now that I'm in college, I've discovered how unique my school was to do this show, which makes it even more special to me. :)
